具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明提供了一种电子设备壳体，包括前壳、中壳和后壳，如图1所示为中壳的结构示意图，所述中壳包括：
位于内部的金属部件100；
位于中部且与所述金属部件100相连的塑胶部件200；
位于外部且与所述塑胶部件200相连的外壳300。
传统的电子设备的中壳为塑料材质，塑料材质其支撑作用时，其强度难以达到要求，滑落至地面时容易破碎，并且给用户展示外表面只能是塑料，且塑料表面的成型质量不好。
因此本发明将中壳分为三部分结构，其内部为金属部件100，金属部件100在中壳中主要为支撑作用，由于金属自身的特质较为坚硬，具有高于塑料强度的特性，因此改变材质后中壳的强度高于传统中壳。位于中部的塑胶部件200主要起连接作用，连接金属部件100和塑胶部件300。
传统中壳是一体式结构，由于中壳本身是塑料材质，导致其外表面仅能够是塑料材质，本发明中金属部件100与外壳300是分离的，因此金属部件100的材质，并不会影响外壳300的材质，外壳材质可以包括金属、玻璃或皮革等多种材质。由于不同用户所爱好的外壳材质不同，本发明可以依据用户需求，在加工中壳时采用不同材质的外壳，以满足多种客户的需求，使得用户体验较好。
经过上述内容可知：本发明提供的壳体能够使壳体强度达到要求，且具有良好的表面成型质量。其中，外部壳体根据工业设计所需的效果可以选择不同的处理方式以及工艺达到不同的工业设计效果。
本发明提供的电子设备壳体包括前壳、中壳和后壳，以上内容为介绍中壳的结构组成，下面介绍中壳是如何与前壳400和后壳500相连的，以便形成一个完整的壳体。
如图2所示，所述金属部件100包括：
设置在所述金属部件100的第一侧的螺孔105，所述螺孔105与前壳卡扣404的第一通孔401大小一致，螺钉402可贯穿所述第一通孔401和螺孔105固定前壳400。
前壳400上包括多个前壳卡扣404，中壳上与前壳卡扣404对应的位置上开有螺孔105，螺钉401贯穿前壳卡扣后锁合在螺孔105内，从而固 定前壳400和中壳，可以理解的是螺孔105的深度大于螺钉402的长度，当螺钉401由于精度的原因造成螺钉402稍微过长时，还可以完全进入螺孔105内，不会形螺钉凸起的现象。螺孔105可以利用攻螺纹的方式获得。
此外，请参见图2所述前壳卡扣404为Z形金属卡扣，所述Z形金属卡扣的折弯处与前壳的显示屏配合。前壳卡扣404为Z形折弯的金属薄片，Z形折弯处是为了避让显示屏，以便显示屏有足够的空间放置在前壳中。
上述实施例中讲述的中壳与前壳400相连的方式，下面介绍中壳与后壳500相连的方式，如图3所示，包括：所述金属部件的第一侧设置有与后壳卡爪501配合的凹槽107。所述金属部件包括：L形卡爪108，所述L形卡爪108用于与所述后壳卡爪501卡接。
后壳500为了与中壳相固定，采用后壳卡爪501的形式卡接在中壳上，为了使卡接的方式更加稳定，在金属部件100还包括L形卡爪108，通过L形卡爪108与后壳卡爪相互卡接，从而使后壳500固定。在具体实施时，本发明发明人发现，后壳卡爪501与金属部件100配合时，金属部件100内侧的空间不足，因此在金属部件的第一侧设置凹槽107，为后壳卡爪501避让，以便后壳卡爪501与金属部件100完整配合。
L形卡爪108可以通过金属折弯工艺折弯金属部件100形成，也可以采用其他方式形成，例如，另外加工一个折弯的L形卡爪，并将该L形卡爪与金属部件100连接，当金属部件100为L形时，塑胶部件200可包裹在L形金属部件的折弯处。这样做有两个好处，一来利用利用注塑工艺加工时，能够达到较高的精度，因此能够提高中壳与后壳500之间缝隙的精度，保证后壳500可以利用该缝隙与中壳卡合，二来可以起到加强固定金 属部件100的作用。
上述实施例详细介绍了中壳，以及中壳与前壳和后壳的配合，电子设备的壳体通常需要与电子设备内部的其他部部件相结合，如图4所示，包括与金属部件100相连的平板600，此处的平板600可以是触控面板也可以是电路面板，平板600可以以焊接的方式与金属部件100相连。
优选的，如图5所示，本发明还提供了一种电子设备壳体，其中，金属部件100为所述平板600折弯后形成的侧壁。即将平板600的一侧采用金属折弯工艺折弯后形成侧壁，将侧壁作为第一金属件100。此方法能够省去第一金属件100与平板600焊接的过程。
中壳包括三个部分，金属部件100、塑胶部件200和外壳，其中金属部件100至少包括一层金属件，所述塑胶部件200包括至少一层塑胶件，即采用一层金属件、两层金属件……多层金属件，一层塑胶件、两层塑胶件……多层塑胶件，当然，金属件的数量和塑胶件的数量不是无穷的，在这里仅表示其数量可以有多个，不限定金属部件和塑胶部件内部的金属件和塑胶件的数量。
本发明中的金属部件100、塑胶部件200具有多种连接形式，具体的包括：
第一种：通过胶水粘贴的方式将所述金属部件与所述塑胶部件相连；
第二种：通过超声波焊接的方式将所述金属部件与所述塑胶部件相连；
第三种：利用注塑工艺在金属部件外侧形成塑胶部件时，将所述金属部件与所述塑胶部件相连。
不同的实现工艺具有的有益效果，一般情况下，金属部件100的侧面 是平整无缺口的，当采用胶水粘贴的方式或者超声波焊接的方式相连时并没有什么不良之处，但是当金属部件100与塑胶部件200采用注塑工艺相连时，若金属部件100的侧面是平整的话，塑胶部件200注塑成型后粘贴至金属部件100上时，容易因抓胶力度不强而脱落，因此本发明还提供了一种包括抓胶结构的金属部件100。
为了实现较强的抓胶力度，该抓胶结构要能够实现以下条部件：在金属部件的第二侧开口小，在金属部件的第一侧开口大，即抓胶结构的形状为锥形结构，以便在通过注塑工艺形成塑胶部件时，塑胶会灌入抓胶结构中，从而使得注塑完成后得到塑胶部件，牢牢地抓住金属部件100，不易脱落。其中，金属部件100上与塑胶部件200相连的一侧为金属部件的第二侧，所述金属部件100的另一侧为金属部件的第一侧。
为了实现抓胶结构，如图6所示，金属部件100包括：
至少一个设置在金属部件100的第一侧的抓胶凹槽101；在金属部件的第二侧上与所述抓胶凹槽101对应位置上设置的第二通孔102，且所述第二通孔102小于所述抓胶凹槽101；
一个抓胶凹槽101和一个第二通孔102形成一个抓胶结构，为了实现较强的抓胶力度，可在金属部件100上设置多个抓胶凹槽101和多个第二通孔102，由此组成多个抓胶结构，多个抓胶结构可平均分布在中壳的周身，以便达到塑胶部件200与金属部件100不易脱落的目的，进而使得外壳300与金属部件100稳稳地结合在一起。
由于传统的加工工艺在一次加工过程中不能实现锥形结构，因此本发明通过抓胶凹槽101和第二通孔102相结合的方式来实现抓胶结构。具 体的，如图6所示，在金属部件的第一侧设置抓胶凹槽101，金属部件的第二侧设置第二通孔102，第二通孔102贯通抓胶凹槽101，并且第二通孔102小于抓胶凹槽101，两者的结合便实现了类似锥形的抓胶结构，利用抓胶结构便解决了塑胶部件200和金属部件100之间容易脱落的问题。
由于金属部件100包括至少一层金属件，因此还可以采用其他方式来实现抓胶结构，例如：金属部件100为两个分开的金属件组成的，针对两个金属件可以采用两种抓胶结构：
第一种：如图7所示，金属部件100包括第一金属件103和与所述第一金属件103相连的第二金属件104；所述第一金属件103上设置有至少一个抓胶凹槽101，所述第二金属件104上与所述抓胶凹槽101对应位置上设有小于所述抓胶凹槽101的第二通孔102。
第二种：如图8所示，金属部件100包括：第三金属件301和与所述第三金属件301相连的第四金属件302。
至少一个设置在第四金属件302的第一侧的抓胶凹槽101；在第四金属件302的第二侧上与所述抓胶凹槽101对应位置上的第二通孔102，且所述第二通孔102小于所述抓胶凹槽101。
所述第四金属件302上与塑胶件200相连的一侧为第四金属件的第二侧，所述第四金属件302的另一侧为第四金属件的第一侧。
第二种方式为第一种方式的改进，第一种方式中，需要在一个金属件上做通孔，之后还要在另一金属件上做凹槽，工序较为繁琐，不利于大量生产，第二种方式中将抓胶结构设置于第四金属件上即可，无需对两个金属件都进行加工，在工序上进行了优化设计。
另外，本发明需要在中壳上做辅助结构以便于与其他部件相连，在第一种方式中需要在第一金属件上做辅助结构，由于第一金属件本身已经做抓胶凹槽，再加工辅助结构时为了防止第一金属件破裂，需要加厚第一金属件的厚度，在第二种方式中可以在第三金属件上做凹槽和第二凹槽等辅助结构，由于第三金属件上没有加工抓胶结构，因此相对于第一种方式而言，，降低了金属部件100的厚度。
当金属部件的为三层、四层或多层时，也可以参照金属部件为两层时的抓胶结构，具体实现形式与上述内容类似，在此不再赘述。
上述介绍了金属部件100的抓胶结构的三种实现形式不论采用哪种方式都能够达到同样的抓胶结构，只是不同的方式有各自不同的优势。其中第二通孔102的结构可以是多种多样的，只要第二通孔102小于抓胶凹槽101即可，优选的，第二通孔102可以为圆形、矩形或三角形。当金属部件100包括两层金属件时，优选的，所述第一金属件103和所述第二金属件104以焊接方式相连，所述第三金属件301和所述第四金属件302以焊接方式相连。以焊接方式相连使两者的结合后的尺寸具有较高的精度，能够减小尺寸误差。
另外，所述第一金属件103、所述第二金属件104、所述第三金属件301和所述第四金属件302为钣金薄金属钣金薄金属厚度通常在6mm以下，从而使得壳体的厚度较薄，用户体验较好。
在图2和图3中，以金属部件100为整体介绍了中壳是如何与前壳400和后壳500相连的，由于金属部件100包括至少一层金属件，因此下面以金属部件100包括两层金属件为例进行说明，第三金属件相当于第一金属 件，第四金属件302相当于第二金属件，因此本实施例仅以第一金属件103和第二金属件104为例进行说明，当金属部件的为三层、四层或多层时，具体实现形式与两层内容类似，在此不再赘述：
如图9所示，当金属件100为两个薄金属件的组合时，所述第一金属件103包括：设置于所述第一金属件103的螺孔105，所述螺孔105与前壳卡扣的第一通孔401大小一致，螺钉402可贯穿所述第一通孔401和螺孔105固定前壳400。所述第二金属件104包括第二凹槽106，当螺钉401长度过长时，多余的部分可以进入第二金属件104的第二凹槽106中，防止产生螺钉凸起的现象。
此外，如图9所示所述前壳卡扣为Z形金属卡扣，所述Z形金属卡扣的折弯处与前壳的显示屏配合。前壳卡扣为Z形折弯的金属薄片，Z形折弯处是为了避让显示屏，以便显示屏有足够的空间放置在前壳中。
上述实施例中讲述的中壳与前壳400相连的方式，下面介绍中壳与后壳500相连的方式，金属件100的在包括两个金属件时，可采用第一金属件和第二金属件为例进行说明：
如图10所示，下面介绍中壳与后壳500相连的方式包括：
所述第一金属件103上设置有与后壳卡爪501配合的凹槽107，所述第二金属件104包括L形卡爪108，所述L形卡爪108用于与所述后壳卡爪501卡接，所述塑胶部件200包裹第二金属件L形卡爪108的折弯处。
在图10中完全可以看出采用两个金属部件的优势：仅在第一金属件103上加工凹槽107即可实现与后壳卡爪501的配合，仅在第二金属件104上通过折弯工艺形成L形卡爪108即可实现与后壳卡爪501的卡接配合， 不仅节省金属材料，还具有加工工艺简单的好处。
上述实施例详细介绍了中壳，以及中壳与前壳和后壳的配合，电子设备的壳体通常需要与电子设备内部的其他部部件相结合，包括与金属部件100与通过焊接方式相连的平板600，当金属部件为两个金属部件的结合时，如图11所示，平板600的连接方式包括：与所述第一金属件103和所述第二金属件104通过焊接方式相连的平板600。此处的平板600可以是触控面板也可以是电路面板。
优选的，如图12所示，本发明还提供了一种电子设备壳体，其中，所述第一金属件103包括平板折弯后形成的侧壁，由于第一金属件100需要与平板600相连，因此可以将平板600与第一金属件100结合在一起，即将平板600的一侧采用金属折弯工艺折弯后形成侧壁，将侧壁作为第一金属件100。此方法能够省去第一金属件100与平板600焊接的过程。
以上为电子设备壳体的结构，本发明的电子设备壳体为强度好，侧壁薄，价格低廉的铁塑结合壳体。
上面实施例中详细介绍了金属部件100的结构，下面介绍外壳300，外壳300即裸露在电子设备外侧供用户观看的外表面，外壳的材质包括：金属、玻璃或皮革。不同的材质展现不同的展示效果。
外壳300通过塑胶部件200与金属部件100相连，具体的可以采用三种方式：
第一种方式：通过胶水粘贴的方式将所述塑胶部件200与所述外壳300相连；
首先以胶水粘贴、超声波焊接或注塑工艺的方式在金属部件100与塑 胶件200连接，然后利用强力胶水将外壳300粘贴至塑胶部件200上。胶水粘贴的方式不牢靠，因此本发明又提供了第二种方式。
第二种方式：通过超声波焊接的方式将所述塑胶部件与所述外壳相连；
首先以胶水粘贴、超声波焊接或注塑工艺的方式在金属部件100与塑胶件200连接，然后通过超声波焊接的方式将外壳300焊接至塑胶部件200上，采用焊接方式的工艺的好处为牢靠不脱落，且工艺较为方便。
以上两种方式都是都需要两个步骤才能够将外壳固定，下面提供一步到位的方式，即第三种方式：利用注塑工艺形成塑胶部件200将金属部件100和外壳300相连的同时，塑胶部件200与所述外壳300相连；将金属部件100和外壳300通过支架固定，将固定好的金属部件100和外壳300连同支架，一起放入注射模具中，通过注塑成型的工艺形成塑胶部件200，塑胶部件200一方面连接金属部件100，一方面连接外壳300，从而实现外壳300的固定。
外壳的材质还可以是塑胶材质，当外壳300塑胶的时候，可以通过二射注塑的工艺，在金属部件100外侧形成一射塑胶(即塑胶部件200)和二射塑胶(即外壳300)，这样在金属部件100外侧有一射塑胶和二射塑胶，两部塑胶工艺使壳体表面具有较高的成型质量。
金属部件100与塑胶部件200相连时可以采用胶水、超声波焊接和注塑工艺三种方式的任一种，塑胶部件200与外壳300相连时也可以采用以上三种方式的任一种，因此中壳的三个部件相连的方式一共有3*3＝9种。在具体实施时可以采用9种的任一种连接方式将中壳的三个部分连接在一起。
本发明可通过以上三种方式固定外壳300，外壳300的材质可以多种多样的，由于客户的需求是不一致的，因此通过相同的工艺即可实现满足不同客户的需求，传统的塑料材质的中壳不能满足客户的多种需求，若需要金属质感的中壳，则只能采用金属材料进行制造，本发明采用相同的工艺流程便可满足不同客户的需求，并且工艺简单。
当金属部件100包括第三金属件301和第四金属部件302，并且外壳300也为塑胶时，可以采用以下方法加工中壳，如图13所示，本发明提供的一种电子设备中壳的制造方法，包括：
步骤S101：将第三金属件和第四金属件焊接在一起形成组合部件，所述第四金属件设置至少设有一个抓胶结构；
步骤S102：将所述组合部件放入双射模具中注塑成型，获得最终的电子设备中壳。
首先在第四金属部件302上加工抓胶结构，并将第三金属件301和第四金属部件302进行焊接得到组合部件，将组合部件通过二射注塑工艺获得一射塑胶和二射塑胶，其中一射塑胶为塑胶部件200，二射塑胶为外壳300，最后形成如图14所示的外壳。
当金属部件100包括第一金属件103和第二金属件104，并且外壳300也为塑胶时，可以采用以下方法加工中壳，如图15所示，本发明提供的一种电子设备中壳的制造方法，包括：
步骤S201：将第一金属件和第二金属件焊接在一起形成第三金属件，所述第一金属件上至少设有一个凹槽，所述第二金属件上设有小于凹槽的 第二通孔，且所述凹槽和所述第二通孔相接触；
步骤S202：将所述第三金属件放入双射模具中注塑成型，获得最终的电子设备壳体。
优选的，还包括：将平板通过焊接工艺与所述第一金属件和第二金属件相连。
本发明提供的电子设备壳体的制造方法，采用本方法制造的电子设备壳体具有强度好，侧壁薄，价格低廉的优点。
